ZF 4699.808.049 GK16 | OEM Genuine Part

Overview

The ZF 4699.808.049 GK16 is a precision-engineered OEM genuine part designed for the clutch pack assembly within heavy-duty ZF transmissions. This component, identified by the SKU 4699.808.049, functions as a critical friction element responsible for transferring torque between planetary gear sets in construction machinery. It sits directly within the hydraulic clutch drum, where it engages under pressure to lock specific gear ratios. Without this part, the transmission cannot achieve proper power flow, leading to operational failure in loaders, graders, and excavators.

Symptoms of Failure

When the ZF 4699.808.049 wears out, operators often notice delayed gear engagement when shifting from forward to reverse. Another common sign is intermittent slipping under heavy load, particularly when climbing grades or lifting. You may also observe dark, burnt transmission fluid with a metallic smell, indicating excessive friction material wear. Finally, erratic shift patterns or harsh engagement can occur as the clutch pack loses its clamping force.

Technical Specifications

Compatibility

This GK16 clutch plate is compatible with ZF WG180, WG200, and WG211 series transmissions commonly found in construction machinery. It also fits select models of the ZF 4WG-200 and 6WG-200 power shift transmissions. Always verify the stack height and spline count before installation, as variations exist between early and late production units.

Installation Context

During a rebuild, the 4699008042: GK16 clutch pack works in tandem with the 4699101107: HOUSING to contain hydraulic pressure. The 4699102151: INPUT shaft drives this assembly, while the 4699103113: OUTPUT hub transfers torque to the final drive. Proper alignment of these four components ensures leak-free operation and long service life.
